hey guys

yes another dilema for me

just finished putting everything togetther after double throttle elimination, and aws solinoid removal

i did just like the vac diagram, and use rob's site

but when i cranked her up, her idle was at 2k but i let her warm up and went to 1500

yes i have a pfc and uses the corect block off plates

yes i did search ( for a while)

please any help would be great

Is the PFS a reprogrammed stock ECU? If so, then you will need to put a 330 - 360 Ohm resistor in the AWS electrical connector.

no its a power fc

not a reprogrammed stock ecu

TPS????

the car boost im not sure at 10 psi but i feel it boosting im just worried about the idle

check all the idle adjustment screws and back them all off completely. I just did the same thing and ran into this as well. I have it down to 1100 with the fans on The real bugger was the fast isle cam adjusting screw. it was causing the high revs the most.

I still have some surging when thecar is in gear and sitting still. I am going to check the TPS adjustment for fine tuning. I think that will take care of the problem. Hoping anyways since there is nothing left in that area to cause the issue

BUT: i also thinki may have a malfunctoning ICS. Idle comes down and surging in gear goes away when it is unplugged.

BTW: this is all with the stock ECU. I have the PFC to put in for him but we have to take th eengine out and rebuild the reman.

I had this issue for a short while too after I did this mod. I readjusted the idle screws, then decided to do the coolant bypass and keep the fast idle cam stuck open. Things are better but different than before. I'm idling at about 1100 now but I was idling at 800-900 before. But I really think the issue is that the block off plates don't seal as well as they should. When I take my UIM manifold off again, I'm going to either put some sealant on the block off plates or find some sort of gasket. Hope this helps a little.

throttle cable too tight?

rotoboy661

i put some sealant before i installed the dbbl throttle block of plate as well as thw aws solinoid and pipe

i think its the tps forsure

i check the uim gasket and tb with carbuerator clear and no leaks

i took off the tps before polishing and installed it with markets but i dont know if i have to agjust it again

anyone know how to adjust the TPS without removing the TB??

thanx

Since i'm in the same diemna, i'm waiting for your results. I've been driving with the ACV disconected which brought the idle down to 1100 but I failed smog miserably. I'd like to have my idle at 700 but not shure if it will hold that low with my streetport. Hopefully it's that screw in the TB trick that's the fix. Post an update please.

I did the McGyver zip tie and had the ACV unpluged and she idles at 700rpm's. I pluged the ACV back in and 2600rpm's. I unplug it again and 1600rpm's. What happened? Maybe I need to to the screw plug thing inside the block off plate?

rotoboy661

and jb weld that bitch

i put sealant in there too
